there is a store in SF that sells it for ATand T and Tmobile.. they sell phones from all over the world. Its $500 w/ new activation. they're called orange communications. (415) 398-2323. I got a phone from them last year..happened to be walking by and saw they had the MPX...

The report from Digitimes references the MPX as if an afterthought see:

"The vendor also intends to discontinue orders of the MPx200 and MPx220 models with CMCS and the MPx with Compal Electronics, indicated the sources...Sources in the China handset market noted that the cancellation of the MPx is partly because the China government has banned unapproved devices using Wi-Fi from being sold in the country. Rather than take the Wi-Fi out of the device, Motorola instead decided to no bother selling the model in China, according to the sources."

It's amazing the Chinese consumer market has that kind of economic power to affect production of such a wonderful product!
